According to a settlement supported by the UN that lifts Russia's blockade of the Black Sea, three additional ships carrying grain sailed from Ukraine on Friday, according to the Turkish defence ministry.
With 33,000 tonnes of grain, the Panama-flagged Navistar departed Odessa for Ireland, according to the report.
And two vessels departed from Chornomorsk port: the Rojen, under the flag of Malta, was carrying 13,000 tonnes of grain to Britain, while the Polarnet, flying the flag of Turkey, was carrying 12,000 tonnes of grain.
It stated that a ship flying the flag of Barbados, the Fulmar, was sailing to the port of Chornomorsk to be filled with grain.
Last month in Istanbul, Moscow and Kiev reached an agreement to begin grain supplies from Ukrainian ports for the first time since Russia invaded its neighbour in February.
On Monday, the first ship departed from Odessa for the Lebanese port of Tripoli carrying 26,000 tonnes of corn.
An inspection team made up of Russian and Ukrainian inspectors gave the Sierra Leone-flagged Razoni the go-ahead to cross the Bosphorus Strait on Wednesday.
An international team that comprises representatives from Turkey, the United Nations, and the two warring parties is in charge of monitoring the ship's transit.
The team said in a statement that the successful passage of the first ship provided "proof of concept" for the viability of the arrangement.
Russia and Ukraine are major suppliers of wheat and other grain.
The halt of almost all deliveries from Ukraine has sent global food prices soaring, making imports prohibitively expensive for some of the world’s poorest nations.
